Feast of Unleavened Bread Day One:
Leviticus 23:4 These are the feasts of the LORD, even holy convocations, which ye shall proclaim in their seasons.
5 In the fourteenth day of the first month at even is the LORD’S passover.
6 And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread.
7 In the first day ye shall have an holy convocation: ye shall do no servile work therein.
8 But ye shall offer an offering made by fire unto the LORD seven days: in the seventh day is an holy convocation: ye shall do no servile work therein.
